Sony understands wearables, for the company's no stranger to Bluetooth headsets, earbuds, and, more recently, smartwatches. Now it's hitting CES with a new vision of SmartWear, a.k.a, basically whatever Sony makes that can pair with a phone and fit comfortable on, or in, your body. The most interesting of the newly unveiled gadgets is the SmartBand, a FitBit Flex-style bracelet that logs your activities throughout the day. It's thin, safe to wear in the shower, and has enough battery life to last for up to five days.
